The man who allegedly mowed down around two dozen people in Melbourne's CBD on Friday, killing four and injuring more than 20 others, has a history of drug use, violence and psychological problems.

James "Jimmy" Gargasoulas, 26, was bailed by a bail justice on the weekend after he was arrested in St Kilda for a number of alleged offences, including family violence and stealing another car, sources said.

Gargasoulas, a father of a number of children, has a second Facebook page on which he recently began posting about religion, God, Satan, heaven and hell.

The comments are rambling and often nonsensical and rant about good and evil. In one chilling post he says an army will be needed to "take me."

On Saturday he posted: "I know exactly how to take you dogs down the power of knowing has revealed and I shall have God's laws re-instated."

And then, on Monday, four days before the Bourke Street rampage: "I declare war on tyranny today you dogs will have the option to either believe in me and his positive energy he offers and stay faithful to me or serve the one who enslaves you at his feet."

Police said the incident is not terrorism related. "This individual is not related to any terrorism activity," Chief Commissioner Graham Ashton said.
